How to Remove Deleted Scanners from Adobe Acrobat
Question details
The user needs to clear old or uninstalled scanner drivers that stubbornly remain in the scanner selection menu when attempting to create a PDF.
- Product
- Adobe Acrobat
- Device & OS
- Windows
- Scenario
- Attempting to create a new PDF document using a connected scanner via the 'File > Create > PDF from Scanner' pathway.
- Observed behavior
- Acrobat continues to display stale scanner entries supplied by TWAIN or WIA drivers, even after the physical scanner and its drivers have been removed from the Windows Device Manager.
Ensure you have administrator privileges on your Windows computer, and disconnect any currently attached scanners before beginning the driver cleanup process.
Uninstall Old Drivers and Reset Acrobat Preferences
Remove outdated scanner software from Windows and clear Acrobat's application cache to refresh the TWAIN/WIA driver list.
Acrobat relies on the TWAIN and WIA driver architectures in Windows to detect scanners. Even if a scanner is disconnected or uninstalled from the Device Manager, residual software or cached preferences can cause it to persist in Acrobat.
Ensure Adobe Acrobat is completely closed and not running in the background.
Open Windows Settings, navigate to 'Apps & features', and uninstall any old scanner software or drivers (such as legacy Brother or Canon utilities).
Reboot your PC to ensure all temporary driver files and background imaging services are completely stopped and released.
Download and install the latest official driver from the manufacturer's website for the scanner you currently intend to use.
Launch Acrobat. If the old entries are still visible in 'File > Create > PDF from Scanner', use the Adobe Acrobat Cleaner Tool to wipe remaining application cache, or hold down Shift + Ctrl (Windows) while launching Acrobat to reset preferences.
Scan directly to PDF with WPS Office
If you are struggling with cluttered driver lists and complex preference resets in Acrobat, WPS Office provides a robust, built-in PDF editor. It easily detects active Windows scanners, allowing you to reliably create high-quality PDFs from physical documents without software conflicts.
- 1. Open WPS Office: Launch WPS Office and navigate to the 'PDF' tab from the main dashboard.
- 2. Access the scanner feature: Click on 'Create PDF' and select the 'From Scanner' option in the menu.
- 3. Select your active scanner: Choose your currently connected scanner from the clean, automatically refreshed dropdown list.
- 4. Scan to PDF: Adjust your preferred scanning settings like color and resolution, then click 'Scan' to instantly generate your PDF document.
Frequently Asked Questions
Why do uninstalled scanners still show up in Acrobat?
Acrobat caches TWAIN and WIA driver entries to load the application faster. When a scanner is uninstalled from Windows, lingering driver files or Acrobat's internal cache can cause the program to retain the entry in the 'Create PDF from Scanner' menu.
Can I delete scanner registry keys to fix this issue?
It is highly discouraged to manually delete registry keys for imaging devices. Doing so incorrectly can corrupt the Windows TWAIN/WIA architecture and stop other working cameras or scanners from functioning properly.
Does the Adobe Acrobat Cleaner Tool fix scanner cache issues?
Yes, the Acrobat Cleaner Tool completely removes residual traces of Adobe Acrobat installations, including corrupted preferences and cached driver lists, giving you a clean slate for hardware detection when reinstalled.
How do I access Windows Device Manager to check my active scanners?
Right-click the Windows Start button and select 'Device Manager'. Expand the 'Imaging devices', 'Cameras', or 'Print queues' categories to verify if your old scanner hardware is still registered by Windows.
